After months of work,
our paper has been accepted, read summaries on the

Mid
term census report of the Surface Stations Project: Is
the U.S. Surface Temperature Record Reliable? - click cover
image at left to download a PDF document. Now at 80%, and
with a majority sample that is spatially well distributed, a
full analysis will be coming in the next few months. We will
however continue to survey stations in the hope of locating
more CRN1 and CRN2 stations due to their rarity.

The upcoming papers will feature statistical
analysis of the nationwide USHCN network in the context of
siting.

Class 1 (CRN1)- Flat and horizontal ground surrounded by a
clear surface with a slope below 1/3 (<19deg). Grass/low
vegetation ground cover <10 centimeters high. Sensors
located at least 100 meters from artificial heating or
reflecting surfaces, such as buildings, concrete surfaces,
and parking lots. Far from large bodies of water, except if
it is representative of the area, and then located at least
100 meters away. No shading when the sun elevation >3
degrees.

Class 2 (CRN2) - Same as Class 1 with the following differences.
Surrounding Vegetation <25 centimeters. No artificial
heating sources within 30m. No shading for a sun elevation
>5deg.

"This is a very important need for the climate science
community, and you are encouraged to obtain this photographic
documentation if you can, and also share with the new website
under development by Anthony Watts"

Special recognition to
five volunteers; Bob Thompson, Eric Gamberg, Russ Steele,
David Smith, and Don Kostuch, who turned summer travels into
survey expeditions. Don Kostuch has surveyed more stations,
and covered a broader geographic area than any other surveyor.
Thanks to all!
